Exbrain 2.0 — A Self-Growing External AI Brain
An AI knowledge system that remembers, compiles, verifies, and evolves on its own.
Claude Code × Obsidian × a 4-layer architecture

What is Exbrain?
There's exactly one reason the most powerful AI model still gives you mediocre output: **it knows nothing about you.**
Exbrain builds an "external brain" that Claude Code reads from and writes to, on top of Obsidian (which is really just a folder of Markdown files). Your days, clients, decisions, and lessons accumulate and get compiled automatically, so that **every session starts already knowing where you are right now.**
- Your memory lives on your own disk, as plain text. No vendor lock-in.
- It keeps working with your laptop closed (via cloud-side scheduled tasks), and you can read it on your iPhone (via iCloud sync).
- Whatever model you swap in next, the brain survives.
What Changed in v2
The single biggest lesson from three months of running v1 (SOUL/MEMORY/DREAMS + clips):
**"Raw logs pile up on their own, but compiled knowledge rots on its own."**
Daily notes and clips (the raw layer) grew fatter every day through automation, while client pages and indexes (the wiki layer) went stale within weeks. v2 fixes this with a **nightly compiler.**
| v1 | v2 | |
|---|---|---|
| Structure | SOUL/MEMORY/DREAMS + a set of folders | 4-layer model (raw → wiki → digest → identity) |
| Front door | None (just CLAUDE.md) | INDEX.md (map + freshness dashboard) |
| Raw → knowledge compilation | Manual (stalls quickly) | Nightly compile runs every night (cheap model) |
| Quality control | weekly-sync.sh (never actually ran) | Weekly lint (regist |
